Since this is an interrupt handler function that triggers the bug, I
don't have to look any earlier than 2003/10/11 since that was when
Bernie added the 'interrupt_handler' attribute to
gcc/config/m68k/m68k.c, or back just before gcc-3.3.3.
I'll check in gcc-3.3.3, gcc-3.3.4, and gcc-3.4.0 to see if its a
regression.
